In all reasonably realistic scenarios that are likely to keep the earth's warming below 1.5 degrees Celsius, emissions will have to begin to decrease rapidly by 2020 at the latest - but from today's perspective, this is unlikely to happen.

This is of course particularly frustrating when you consider how much has been talked about climate protection since the start of the Fridays for Future demonstrations. Greta Thunberg also said in Davos that she couldn't complain about a lack of being heard: she was heard all the time. But hearing is not action.
